BR-CO-17 — Category tax amount is wrong (BT-117)

• Standard: EN16931
• Severity: fatal
• Business Terms: BT-117, BT-116, BT-119

Meaning

"VAT category tax amount" (BT-117) = "VAT category taxable amount" (BT-116) × ("VAT category rate" (BT-119) / 100), rounded to two decimals.

Possible causes

• BT-117 (TaxSubtotal/TaxAmount) was not rounded to two decimals.
• The rate BT-119 or the taxable base BT-116 in the breakdown does not match the amount.

How to fix it

• Compute BT-117 (cbc:TaxAmount) as BT-116 × BT-119 / 100 and round half-up to two decimals.

Affected fields

• /ubl:Invoice/cac:TaxTotal/cac:TaxSubtotal/cbc:TaxAmount
• /ubl:Invoice/cac:TaxTotal/cac:TaxSubtotal/cbc:TaxableAmount
• /ubl:Invoice/cac:TaxTotal/cac:TaxSubtotal/cac:TaxCategory/cbc:Percent
